6.7L – 175 inch Wheelbase – Thump/Whine/Knock Noise From The Fuel Tank After Performing TSB 21-2057 – 2020-2022 Ford F-Super Duty

NHTSA ID Number: 10207050

Manufacturer Communication Number: SSM 50380

Summary

Some 2020-2022 F-Super Duty pickup vehicles equipped with a 6.7L engine, 175 inch wheelbase, and built on or before 23-Sep-2021 may exhibit a thump/whine/knock noise from the midship fuel tank at idle or during key on, engine off (KOEO) after performing TSB 21-2057. The noise may be more pronounced at fuel levels at or below 1/4 tank. This may be due to the fuel pump. To correct the condition, replace the fuel pump and sender assembly with service part HC3Z-9H307-AP. For claiming, use causal part 9H307 and applicable labor operations in Section 08 of the Service Labor Time Standards (SLTS) Manual.

  • How It Works: Doc's Fuel Filters remove contaminants like separate water from dirt, rust, and debris, protecting fuel system components and ensuring peak engine performance.
